[Elecraft] Trying to get help, one more time...

	Does anyone (i.e. Elecraft) know the Auxbus protocol? And is the spec
available?

	I beleive, in trying to find out why the 8R voltage is at 6.43v, I blew the
MCU (controller board) AuxBUS output.

	I only see pin 40 drop a few tens of millivolts during a band change
request.

	The IOC starts and stops the clock on power up, no relays change and that's
all the RF board does.

	Info 080 is displayed during powerup and on a band change request.

	That says the IOC or the AuxBUS is in trouble.

	Since I didn't get any response for my last question, I'm hoping this one
is more interesting to the readers.
